I've bought from them. They were taking orders for Lokomotiv jerseys last year with the intent of donating their profits from those jerseys to the fund for families. The jersey I bought is actually a bit small for me as I misjudged the sizes in relation to US sizes but otherwise no other problems.
I have ordered from Jerseyhub on several occasions and they have always been great. Last year I placed an order close to Christmas and they made sure I had it with time to spare. Very happy with them.
On a side note, I contacted Lutch USA and have a Yugra Khanty-Mansiysk junior jersey coming to me. This is what they quoted me when I spoke with them, "By the way, anytime you see our logo on any jersey, we can 100% manufacture them, just send us an image."
Hope this info is helpful. Have six KHL jerseys myself and people are always asking me about them when I wear them.
